Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector which is fixed to an electronic circuit board or the like and is capable of connecting and disconnecting a flat cable for transmitting and receiving a signal to and from another electronic circuit board or another electronic device. The present invention relates to a cable removal jig for removing the leading end of the connected flat cable from the connector body.

[0002]

2. Description of the Related Art In recent years, with the miniaturization of electronic circuit boards, miniaturized connectors for connecting / disconnecting flat cables for transmitting / receiving signals to / from other electronic circuit boards or other electronic devices have become smaller. Therefore, high precision is required for the work of inserting and removing the flat cable into and from this connector. Also,
A connector with a lock claw, which has a mechanism for locking the tip of the inserted flat cable, has come into wide use.

When a flat cable is connected to the conventional connector with a lock claw, the tip of the flat cable is inserted into the connector in the unlocked state, and then the lock claw is pushed in to lock. When the flat cable locked and connected to the connector body is to be removed, the lock claw is pulled out in the cable removal direction to release the lock.

Incidentally, since this type of connector is well known, no reference is given to it.

[0005]

In the above-mentioned prior art, when the tip lead portion of the flat cable is pulled out from the small connector with the lock claw, the lock claw is released directly by fingers. There is a risk of breaking the lock claws beyond the limit of movement or damaging the connector body, and in order to release the small lock claws that lock the tip of the flat cable with your fingers,
There was a problem of low work efficiency.

Further, when the lock claw releasing operation is repeated a number of times, there is a problem that the operator's fingers are pained, which further lowers the work efficiency. The object of the present invention is to solve the above-mentioned problems of the prior art, to facilitate the work of removing the flat cable connected to the connector with the lock claw, and to facilitate the leading end of the flat cable without causing damage to the connector body. It is to provide a connector removing jig that can be removed.

[0007]

In order to achieve the above object, the present invention provides two locking claws 7, 7'for locking the leading end of the flat cable 6 pushed in the insertion direction of the flat cable. From the connector main body 5 provided with both ends of the tip lead portion to the lock claws 7, 7 '.
In a cable removing jig for releasing the lock of the connector and removing the lead portion of the end of the flat cable, the connector body 5 is attached to each of the lock claws 7 and 7'at the tip.
Stopper portion 3 that connects the forked portions 2 and 2 ′ that collide with each other in the removal direction of the tip lead portion from the side and the forked portions 2 and 2 ′ and abuts the rear end portion 8 of the connector body 5.
And a handle portion 4 connected to the stopper portion 3.

[0008]

When the flat cable is pulled out from the connector, the bifurcated portions 2 and 2'of the cable pulling jig 1 are attached to the abutting portion 71 of the locking claws 7 and 7'from the connector body 5 side.
The flat cable 6 is pushed out in the removing direction by hitting 71 '. By pushing out the lock claws 7 and 7 ′, the lock of the tip lead portion 61 of the flat cable 6 is released.

As a result, the flat cable 6 can be pulled out after the connection with the connector body 5 is released. When the cable removing jig 1 is further pushed out, its stopper portion 3 abuts on the rear end portion 8 of the connector body 5, and further pushing out is prevented. Therefore, it is possible to prevent the lock claws 7 and 7 ′ from being broken and the connector body from being broken by pushing the lock claws 7 and 7 ′ beyond the limit.

Further, with this configuration, it is not necessary to release the lock claws 7 and 7'by fingers, and the work of pulling out the flat cable can be performed with one hand, and the work efficiency is improved.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a perspective view for explaining the structure of an embodiment of a cable extracting jig according to the present invention, in which 1 is a cable extracting jig, 2 and 2'is a forked portion, 3 is a stopper portion,
Reference numeral 4 is a handle portion.

In the figure, the forked portions 2 and 2'are provided with an interval corresponding to the interval of the locking claws of the connector, and the connecting portion constitutes the stopper 3. A handle portion 4 for an operator to hold is connected to the stopper 3, and the handle portion 4 is slightly bent with respect to the bifurcated portions 2 and 2 ′ and the stopper 3 in order to facilitate the work. .

FIG. 2 is a perspective view for explaining a state in which the flat cable is connected and fixed to the connector body.
Is a connector body, 6 is a flat cable, 7 and 7'are locking claws, 71 and 71 'are abutting portions, and 8 is a rear end portion of the connector body. In the figure, the flat cable 6 has a lock claw 7 formed by inserting the tip lead portion into the connector body 5,
7'is pushed into the connector body 5 side as shown by the arrow A and locked.

FIG. 3 is an explanatory view of the work of pulling out the flat cable locked to the connector body. The same reference numerals as those in FIGS. 1 and 2 correspond to the same portions, and 61 is a tip lead portion of the flat cable 6. is there. In the figure, when removing the flat cable 6 from the connector body 5,
With the cable removal jig 1 provided with the forked portions 2 and 2'having a gap that matches the gap between the lock claws 7 and 7 ',
The bifurcated portions 2 and 2'are attached to the abutting portions 71 of the lock claws 7 and 7 '.
Abut on 71 'and push in the direction indicated by arrow B.

As a result, the lock claws 7, 7'are pulled out in the direction of arrow C, and the lock of the tip lead portion 61 of the flat cable 6 in the connector body 5 is released. In this state, the flat cable 6 can be pulled out from the connector body 5. Then, when the cable removal jig 1 is further pushed out in the direction of the arrow B, the stopper portion 3 abuts on the rear end portion 8 of the connector body 5, and further pushing out cannot be performed. Therefore, it is possible to prevent breakage caused by excessively pushing out the lock claws 7 and 7'in an attempt to remove the flat cable 6.

Further, since the work of pulling out the flat cable 6 can be performed only by one-handed operation by the operator, the work efficiency can be remarkably improved, and it is not necessary to release the lock claw with fingers as in the conventional case. . FIG. 4 is a cross-sectional view of an essential part for explaining a connection state between the connector body and the flat cable described above, and shows a state in which the tip lead portion 61 of the flat cable 6 is locked by the lock claw 7.

That is, the tip lead portion 61 of the flat cable 6 is brought into contact with the conductor portion 51 of the connector body 5 and locked by pushing the lock claw 7. FIG. 5 is a cross-sectional view of an essential part for explaining a connection release state between the connector body and the flat cable described above, and shows a state in which the lock of the flat cable 6 is released by pulling out the lock claw 7.

That is, in the flat cable 6, the lock claw 7 is formed by the operation described in FIG.
The lock is released by pulling it out from, and the connection with the conductor portion 51 is released, and it is pulled out in the direction of arrow D. As described above, according to the present embodiment, it is easy to remove the flat cable connected to the connector with the lock claw,
The leading end of the flat cable can be easily removed without damaging the lock claw or the connector body.

[0019]

As described above, according to the connector removing jig of the present invention, it is not necessary to release the lock claw with fingers, and the flat cable can be removed with one hand, thus improving the work efficiency. . By standardizing the removal work of the flat cable, it is possible to avoid damage to the lead portion of the tip of the flat cable, and to prevent a connection failure or the like due to frequent insertion and removal work of the flat cable and the connector.
